To all whom it may concern: of the beer from one of the pairs of pipes to Be it known that I, DANIEL L. HOLDEN, a the other.

These collars f g are secured by bolts 5,so that tight joints are formed between the said boxes and pipes. There are similar boxes 71, into which the respeetive ends of pairs of internal pipes b are fitted, and I provide collars i and packings 8 around the ends of said inner pipes to form tight joints between them and said boxes. 'lhese boxes h are open at one end and provided with removable heads 7., which are pivoted to the boxes by bolts at 9, and swingingeycbolts I are provided and pivoted to the boxes and adapted to enter notches in the removable heads to clamp the same to place against the open ends of the boxes. These boxes h form return-passages between the ends of the pairs of inner pipes b, and whenever it becomes necessary to clean out or swab the inside of the pipes band boxes h the eyebolts Z are loosened and swung back, and the heads 7.1 swing on their pivots J, and access is thereby given for this cleansing operation.

I do not limit myself to the construction of the heads k, as simple plates of metal fitting upon the ends of the boxes h and held in place by hook-ended bridge-bars and central screws may be employed with equal facility. I claim as my invention 1 1. The combination, with the pairs of external pipes a for cooling liquid, the boxes l c, to which such pipes are connected and into which they open, and the pairs of internal pipes I) for liquid to be cooled, passing through the pipes at and boxes e and projecting beyond, of the boxes 7a, connected to the ends of the pairs of pipes I) and open at one end, and removable heads or covers to said boxes, by which access can be had to the interior of the internal pipes and boxes for purpose of cleaning, substantially as specified.

E2. The combination, with the pairs of external pipes a for cooling liquid, the boxes 0', to which such pipes are connected and into which they open, and the pairs of internal pipes 12 for liquid to be cooled, passing through the pipes a and boxes 6' and projecting beyond, of the boxes 71, connected to the ends of the pairs of pipes b and open at one end, the removable heads or covers 7r, pivoted by bolts 9 to the boxes, and the swinging eyebolts Z, pivoted to the boxes and adapted to engage and secure the covers 7:, substantially in the manner and for the purposes set forth.

Signed by me this 16th day of December, A. D. 1889.
